At least 45 Indian workers were evacuated from a riot at shipbuilding company PT Drydocks World Graha dockyard at Tanjung Uncang in Batam, Riau Islands province, Thursday.

Riau Island Police deputy chief Sr. Comr Bambang BS said that the 45 people were evacuated by a police patrol boat to the local police headquarters for safety reasons.

The police, he said, were still investigating the riot, which was reportedly caused by a humiliating statement by one of the Indian managers at the company, who said that Indonesians were "stupid".

Hari Ariadewa of the company's quality control unit said that the riot was sparked by a statement by an Indian supervisor, identified as Mr. Ganesh, who berated one of the Indonesian workers for making a mistake.

This statement was frequently uttered by the Indian supervisor to his subordinates, Hari said.

“The derogatory remark sparked anger among [thousands of] Indonesian workers. A riot then spread to other units,” he added.

Two of the Indian workers were seriously injured, dozens of vehicles and other facilities were set alight and a storage warehouse was destroyed.
